With Pink Floyd resting like Monty Python’s ex-parrot, it is once again Roger Waters’s job to assume the Floydian mantle, and he’s assembled a crack octet to take with him on the road, with guitarists Snowy White, Andy Fairweather-Low, and Dave Kilminster filling in for David Gilmour. The 63-year-old has mounted a two-hour-and-40 minute show that’s as high on spectacular sonics and visuals as you’d expect. The second half last Friday at the Tweeter Center was the entirety of The Dark Side of the Moon, and it sounded as resonant 33 years after the fact: trippy, grand, orgasmic, cynical, resigned, resplendent, sad.

Like much of Floyd’s material, Dark Side has as its basis the drug-exacerbated crack-up of Floyd founding genius/madman Syd Barrett. When he began the tour, Waters didn’t know Barrett would pass away this summer, but Barrett’s actual death — as opposed to his protracted creative death — added a level of poignancy. As did the clips on the backing scrim of a young Barrett and band cavorting about during the boom-and-gloom opener, “In the Flesh,” and showing up again during the throbbing “Set the Controls for the Heart of the Sun” and the elegiac “Shine On You Crazy Diamond.”

Dark Side sounded note-perfect: for “Money” there was an image of an LP, a turntable, and a tone-arm on screen, and the “Shorter of breath/One day closer to death” line in “Time” hit the gong of truth again. Waters — steely-eyed and sporting a toothy grin — did not mind stepping back occasionally to play bass or strum acoustic guitar, and saxophonist Ian Ritchie and the guitarists held sway as George W. Bush and “Mission Accomplished” went up on screen in “Us and Them.” They closed with “Another Brick in the Wall (Part 2),” and I couldn’t escape the thought that the children’s choir that sang “We don’t need no education/We don’t need no thought control” in 1979 on The Wall (and was sampled here) was now in early middle age.

Sound Czech Tom Stoppard’s Rock ’n’ Roll begins in 1968 in an English garden, where a piper perched atop an ivied wall is serenading a stretched-out blonde flower child.

Syd Barrett Without meaning to, Barrett invented one of rock’s enduring archetypes: the visionary who burns brightly just long enough to become a bona fide star before plummeting into introversion and, in this case, a silence lasting more than 30 years.

Master at work The best guitarists can always be recognized by their sound, even if they spend their careers swapping amps, effects, or instruments.

Rising sun What else could a mid-level, socially conscious band of affable guys writing listenable pop music want? To lose their collegiate reputation.

Cursed films At some point while watching the features in the Harvard Film Archive's "Le Film Maudit" ("cursed films") series — perhaps during the "Circle of Shit" chapter in Pier Paolo Pasolini's SALÒ, OR THE 120 DAYS OF SODOM — you might ask yourself, which is more cursed, the movies or anyone unfortunate enough to be watching them?

Emergency music Convicted murderer Gary Gilmore’s last words were, “Let’s do it!” The next sound was gunfire.

TATTOO YOU | April 06, 2010 Dr. Lakra is no more a real doctor than is Dr. Dre or Dr. Demento. The 38-year-old Mexican tattoo artist’s real name is Jerónimo López Ramírez. As for “lakra,” it means “delinquent.” Or so I thought.
